6 Claims.

The invention relates to a method for producing lambskin powder-puffsand the like, and to apparatus for producing the same.

An object of the invention is to provide an improved method forexpeditiously producing lambskin powder-puffs and the like, whereby tominimize cutting of the wool or hair around the edges of the articlesand to avoid irregular or uneven edges.

Another object of the invention is to provide apparatus for facilitatingthe cutting of the lambskin.

Referring to the accompanying drawing,

Fig. l is a sectional elevation of an apparatus constructed inaccordance with the invention and suitable for carrying out the methodof the invention, a lambskin being shown in cutting position;

Fig. 2 is a plan view of a lambskin which has been cut by the method,and

Fig. 3 is a perspective view of a lambskin powder-pufl' produced by themethod.

In the drawing, in designates a flat-topped member on which is suitablysecured a flat panel II to form a table. The panel II is preferablyprovided with a resilient pad [I inserted in a circular opening I!formed in the panel, the upper surface of the pad being approximatelyflush with or slightly above the top plane of the panel. The pad ispreferably formed of a circular section of lambskin with the wool I2 up.

The panel ll forms a support for a tanned lambskin I 4 which is restedthereon with its wool M in contact with the panel and with the resilientpad l2.

A cutter I 5, preferably a rotary cutter with an annular knife-likecutting edge, is supported above the table in any suitable manner and ismovable downwardly into cutting engagement with the flesh side of thelambskin. The cutter is arranged centrally above the resilient pad l2,the pad being larger in diameter than the cutter. The cutter is hereshown to be in the form of an inverted cup with cylindrical walls andhaving a central shank l6 which is clamped in a suitably driven rotarychuck H. The web of the rotary cutter is provided with one or moreapertures it through which the operator may view the lambskin and theprogress of the cutting. In some instances, the flat-topped table memberll and chuck I'I may be parts of an ordinary drill-press. Instead ofmoving the cutter down to the work, it is obvious that the work may bemoved up to the cutter.

The lambskin H, with its wool l4 sheared to a uniform length, is placedon the panel or table I I with its flesh side up, and is shifted by theoperator along the table to bring a suitable portion of the skin beneaththe elevated rotary cutter, which latter is then depressed into cuttingengagement with the skin, the operator holding the lambskin in position.The cutter is moved downwardly just far enough to cut through the skinproper without cutting the wool. During the cutting operation the skinwfll yield downwardly to some extent as indicated in Fig. 1, because ofthe resilience of the wool. The pad It provides additional cushioningeffect and also exerts a frictional effect on the lambskin. The cutteris then raised and after the lambskin is shifted along the table toanother position, the cutting operation is repeated. Successive cuts aremade in the same manner, and after all the cutting operations arecompleted, the several powder-pufis l9 thus formed are separated fromthe lambskin, the powder-puffs having adhered to the lambskin by themeshing of the wool fibres.

The skin portion of each powder-puff has a smooth regular edge, and thefull amount of wool is left around the edge of the powder-puff so thatafter the wooly edge spreads out it will have a regular appearance.

The method of the invention may also be used for producing otherarticles of hair-bearing material, such as mops, polishers, and buttons,where it is desirable to avoid cutting the hair at the edges of thearticles and to obtain regular edges.

What we claim as new and desire to secure by Letters Patent is:

1. Apparatus for producing a pad from a hairbearing skin, comprising aresilient support on which the skin is placed flesh side up, and arotary cutter engageable with the skin to cut through the skin properbut not into the hair, saidresilient support being yieldable downwardlyunder the pressure of the cutter against the skin.

2. A cutting table for hair-bearing skins, comprising a support on whicha skin is placed with its flesh side up, said support having a recess,and a resilient member in said recess yieldable downwardly to cushionthe portion of the skin to be cut.

3. Apparatus for producing a circular pad from a hair-bearing skin,comprising a support on which the skin is placed flesh side up, and acutter above the support rotatable on an axis perpendicular to the skinand having a smooth knifelike skin-engaging cutting edge movable in acircutting edge concentric with said axis and en- (Seal) gageable in anaxial direction with the skin.

5. Apparatus for producing a circular pad from a hair-bearing skin,comprising a support on which the skin is placed flesh side up, and acutter above said support rotatable on an axis perpendicular to the skinand having an annular cutting edge concentric with said axis andengageabl'e in an axial direction with the skin, said cutter beingapertured for viewing the skin M9? throush.

6. The method for producing a lambskin powderpufl or the like, whichconsists in presenting the flesh side of a lambskin having hair thereonto a cutter, supporting the hair side on a yielding support, eflecting arelative rotation of the cutter and lambskin about an axis perpendicularto the sidn, and applying the cutter to the skin in an axial directionto cut out a circular section oi the skin.
